Scan PDF: Document Scan & OCR turns your phone into a powerful document scanner. Everything runs on your device, and it works offline. SCAN ANYTHING Automatic edge detection and perspective correction give you sharp, flat scans of documents, receipts, ID cards, whiteboards and notes. Auto / Grey / Black-and-white filters plus a brightness slider make every page as clean and readable as print. MAKE A PDF INSTANTLY Export multi-page PDFs (A4 / Letter / fit-to-image), tune compression to keep files small, then share to Gmail, Drive, Messages — or print directly. Lock a PDF with AES-256 encryption. Add your own watermark, timestamp and footer (name + logo). OCR — EXTRACT AND SEARCH On-device OCR pulls editable text out of your scans, in Latin scripts plus Chinese, Japanese, Korean and Hindi. Copy it, share it, or search your whole library by what is written inside your documents. On export, keep the photo and add an invisible searchable text layer, or rebuild the page as selectable vector text — razor sharp at any zoom and remarkably small. SCAN QR CODES AND BARCODES Read QR codes and barcodes on device; open links straight from the result. MERGE, SIGN AND ORGANISE Combine several PDFs and images into one file. Sign and annotate by hand, reorder pages, rotate, delete the ones you do not need, and export any page to your photo library as JPG or PNG. Keep everything tidy in folders with instant search. YOUR DATA STAYS ON YOUR PHONE Every scan, OCR pass and PDF is processed on your device and never uploaded to our servers — no account, no cloud sync, works in airplane mode. Lock the app with a PIN or Face ID / Touch ID, and protect any PDF with AES-256. Available in 17 languages, including English, Tiếng Việt, 简体中文, 日本語, 한국어, Español, Português, Bahasa Indonesia, हिन्दी, العربية and more. The free version is ad-supported; our advertising partners may use your device identifier.

Important bug fixes: • No more losing a scan when acting on the last page. • No accidental document deletion while exporting or printing. • Setting the app-lock PIN now asks you to confirm, so a typo can't lock you out. Thanks for using Scan PDF! ### 1.0.2 — 2026-07-21 Performance improvements and bug fixes for a faster, smoother scanning experience. Thanks for using Scan PDF! ### 1.0.1 — 2026-07-17 Our first big update — cleaner scans, many more languages. AUTOMATIC BACKGROUND CLEANUP Scanning on a wooden desk and a strip of it crept into the edge of your page? The app now cleans those strips away. Importantly, it crops nothing, so your text, signatures and stamps are always kept intact. Can be turned off in Settings. 17 INTERFACE LANGUAGES Added Chinese, Japanese, Korean, Thai, Russian, German, French, Spanish, Portuguese, Indonesian, Turkish, Hindi, Bengali, Arabic and Urdu. Arabic and Urdu lay out correctly right-to-left. OCR IN MORE SCRIPTS Beyond Latin scripts, the app now recognises Chinese, Japanese, Korean and Hindi text. Pick your script in Settings. INSTANT PAGE ROTATION A dedicated 90° rotate button in the editor — tap and it turns, no waiting. TEXT PDFs NOW RESPECT PAGE SIZE Choosing A4, Letter or "fit to image" now actually applies when exporting a text PDF — it always produced A4 before. ### 1.0 — 2026-07-16 No release notes. ## More apps by NKKtech Global Pte.
